Hi. I desire to change my plastic nut in my Squier Affinity. the nut has particular dimensions. They are: Length: 41mm Widht : 3mm Heigth : not simple to measure (3 or 4 mm) I don't find any similar nut in the net. I don't want to work on it much.. I desire something ready to go... Could you help me to find a really good replacement?
